Motion Detection S/W

bbwannabe · 31-08-2007, 14:56

I've got a small camera setup in my room for security reasons (i.e things being thrown at window) pointing outside, but i can't find a suitable application to make it effective. At the moment, i'm using virtualdub to capture the streams through a capture device as an avi file. But it doesn't do motion detection, so the file ends up in GBs for less than a days recording and most of the time, it's pretty much the same image all day. It doesn't timestamp it either, which can make things difficult if i need to jump to a time straight away and don't know where it is.

Any and all suggestions welcome. If it's able to encode it to a custom codec and allows a direct and adjustable camera adjustments (sharpness, hue, saturation, etc) then that'd be a great extra.

Thanks.

Which camera are you using to do this and what are you saving the avi file as .?

I have an axis network camera used with 'motion' which emails me when it detects movement. It's probably a bit complicated if you don't know linux but it
works a treat, was nice to see the neighbours cat using my flowerbed as a toilet when I was on holiday.

He's not using linux though (AFAIK)

I haven't seen a free windows application to rival motion. It's the dogs.

Here you can see the rising sun activated the motion detector. Motion drew a box around the movement and recorded a couple of shots with timestamps. The number of 'moved' pixels is in the top right.
It then adjusted to the new environment (ie. sunnier) ready for any new 'changes'.

http://www.maplin.co.uk/Module.aspx?...9-6&T=12542556 - this is the camera i'm using. It's better for short range use than long range, as it loses sharpness over distance. And it doesn't cover a wide area that well - the areas outside of the centre blur as it goes further away. I tried a flexible web-cam, but framerate was poor, and doesn't work in normal daylight (the view is totally white). Colour is slightly green, a little dark at time (hence the need for colour/contrast adjustments), and doesn't work well at night..

The file gets saved using the divx codec (ffdshow ??)

You're right. I'm on Windows XP. Motion does look pretty neat, but i wonder if it just takes snapshots.

It can stream to mpg format at 25fps.
